| 1 | Weighted Markov chains for forecasting and analysis in Incidence of infectious diseases in jiangsu Province,China显示文摘This paper first applies the sequential cluster method to set up the classification standard of infectious disease incidence state based on the fact that there are many uncertainty characteristics in the incidence course.Then the paper presents a weighted Markov chain,a method which is used to predict the future incidence state.This method assumes the standardized self-coefficients as weights based on the special characteristics of infectious disease incidence being a dependent stochastic variable.It also analyzes the characteristics of infectious diseases incidence via the Markov chain Monte Carlo method to make the long-term benefit of decision optimal.Our method is successfully validated using existing incidents data of infectious diseases in Jiangsu Province.In summation,this paper proposes ways to improve the accuracy of the weighted Markov chain,specifically in the field of infection epidemiology. | Zhihang Peng Changjun Bao Yang Zhao Honggang Yi Letian Xia Hao Yu Hongbing Shen Feng Chen | 2010 | The Journal of Biomedical Research2010，24，3： | 10 |
| 2 | Prevalence and risk factors of HIV and syphilis,and knowledge and risk behaviors related to HIV/AIDS among men who have sex with men in Chongqing,China显示文摘High HIV prevalence and incidence burdens have been reported in men who have sex with men(MSM)in Chongqing,China.We aimed to estimate the prevalence of HIV and other sexually transmitted infections(STIs),to appraise the knowledge and risk behaviors related to HIV/AIDS among MSM,and to analyze the possible causes of deviation between behavior and knowledge to make better strategies.We recruited 617 MSM from February to July in 2008 by using a respondent-driven sampling(RDS) method in Chongqing,China.Through the collection of questionnaire-based data and biological testing results from all objects,we launched a crosssectional survey.STATA/SE was used for data analysis by frequency,ANOVA,rank sum test and logistic regression models.MSM with syphilis(OR=4.16,95%CI:2.35-7.33,P<0.0001) were more likely to be HIV infected.Being a company employee(OR=3.64,95%CI:1.22-10.08,P<0.0001) and having bought male for sex(OR=3.52,95%CI:1.10-11.32,P<0.034) were associated with a higher probability of syphilis.MSM with younger age,higher education and greater monthly income had a higher mean knowledge score.MSM who had HIV testing had a higher mean knowledge score than those who never had.Students,venues for finding sex partners by Internet and homosexuals in MSM had a higher mean knowledge score compared to other occupations,venues for finding sex partners and sexual orientation.There is an urgent need for delivery of barrier and biomedical interventions with coordinated behavioral and structural strategies to improve the effect of HIV interventions among MSM. | Wenzhe Ma Guohui Wu Hui Zheng Wenjuan Zhang Zhihang Peng Rongbin Yu NingWang | 2016 | The Journal of Biomedical Research2016，30，2： | 9 |
| 3 | Estimation and Projection of the HIV Epidemic Trend among the Migrant Population in China显示文摘Objective The migrant population is a vulnerable group for HIV infection in China.Understanding potential epidemic trends among migrants is critical for developing HIV preventative measures in this population.Methods The Estimation and Projection Package (EPP) model was used to process prefecture and county-level surveillance data to generate HIV prevalence and epidemic trends for migrant populations in China.Results The prevalence of HIV among migrants in 2009 was estimated at 0.075% (95% CI:0.042%,0.108%) in China.The HIV epidemic among migrants is likely to increase over the next 5 years,with the prevalence expected to reach 0.110% (95% CI:0.070%,0.150%) by 2015.Conclusion Although the 2009 estimates for the HIV/AIDS epidemic in China indicate a slower rate of increase compared with the national HIV/AIDS epidemic,it is estimated to persistently increase among migrants over the next 5 years.Migrants will have a strong impact on the overall future of the HIV epidemic trend in China and evidence-based prevention and monitoring efforts should be expanded for this vulnerable population. | MENGXiaoJun WANG Lu Susan CHAN Kathleen Heather REILLY PENG ZhiHang GUO Wei DING GuoWei DING ZhengWei QIN QianQian | 2011 | Biomedical and Environmental Sciences2011，24，4： | 8 |

| 5 | Modeling the Epidemic Trend of the 2019 Novel Coronavirus Outbreak in China显示文摘A new coronavirus disease(COVID-19)with infection by a novel coronavirus named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has spread globally since December 2019.By 22th September 2020,more than 200 countries worldwide have reported about 30 million confirmed cases and more than 950,000 deaths.1 China has reported a total of 85,307(including 2,758 imported)cases and 4,634 deaths. | Mingwang Shen Zhihang Peng Yanni Xiao Lei Zhang | 2020 | The Innovation2020，1，3： | 3 |
| 6 | A survey of HIV infection and related high-risk factors among men who have sex with men in Suzhou,Jiangsu,China显示文摘A cross-sectional study using the snowball sampling method was conducted in May 2008 to investigate human immunodeficiency virus (HIV) infection status and related high risk factors among men who have sex with men (MSM) in Suzhou city of Jiangsu province. The researchers carried out a face-to-face questionnaire interview among MSM, and collected their blood samples to test for HIV and other sexually transmitted diseases (STDs). Among the 280 respondents, 91.1% had homosexual acts in the past 6 months and 87.5% had multiple homosexual partners; 46.4% had heterosexual sex in the past 6 months and 33.1% had multiple heterosexual partners. The rate of continued condom use was 44.3% in homosexual sex in the past 6 months, while the rate in heterosexual sex was 33.9%. Laboratory test results showed that the prevalences of HIV and syphilis were 7.1% (20/280) and 15.0% (42/280), respectively, but no HCV-positive person was found. In the multivariate logistic regression model, subjects with a monthly income of more than RMB $ 1,000 (OR=4.83,95% CI=1.44-16.22), subjects who often went to bars for sexual partners (OR=2.25, 95%CI=1.21-4.20), and subjects who had more than one sexual partner in the past 6 months (OR=0.49, 95%CI=0.25-0.97) and had sex with fixed sexual partners in the past 6 months (OR=0.42, 95%CI=0.25-0.75) were significantly associated with the rate of continued condom use in homosexual sex in the past 6 months. Unprotected sex and multiple sexual partners were more common among MSM in Suzhou city; furthermore, the prevalences of HIV infection and syphilis were relatively high. HIV preventive measures should be designed to address these risk factors and control the spread of HIV among MSM. | Hongling Bai Xiping Huan Weiming Tang Xin Chen Hongjing Yan Xiaoyan Liu Haitao Yang Zhihang Peng Xiuping Zhao Rongbin Yu Hao Yu Feng Chen | 2011 | The Journal of Biomedical Research2011，25，1： | 2 |
| 7 | Linking key intervention timings to rapid declining effective reproduction number to quantify lessons against COVID-19显示文摘Coronavirus disease 2019(COVID-19)is currently under a global pandemic trend.The efficiency of containment measures and epidemic tendency of typical countries should be assessed.In this study,the efficiency of prevention and control measures in China,Italy,Iran,South Korea,and Japan was assessed,and the COVID-19 epidemic tendency among these countries was compared.Results showed that the effective reproduction number(Re)in Wuhan,China increased almost exponentially,reaching a maximum of 3.98 before a lockdown and rapidly decreased to below 1 due to containment and mitigation strategies of the Chinese government.The Re in Italy declined at a slower pace than that in China after the implementation of prevention and control measures.The Re in Iran showed a certain decline after the establishment of a national epidemic control command,and an evident stationary phase occurred because the best window period for the prevention and control of the epidemic was missed.The epidemic in Japan and South Korea reoccurred several times with the Re fluctuating greatly.The epidemic has hardly rebounded in China due to the implementation of prevention and control strategies and the effective enforcement of policies.Other countries suffering from the epidemic could learn from the Chinese experience in containing COVID-19. | Zhihang Peng Wenyu Song Zhongxing Ding Quanquan Guan Xu Yang Qiaoqiao Xu Xu Wang Yankai Xia | 2020 | Frontiers of Medicine2020，14，5： | 2 |
| 8 | Associations of IFN-γ rs2430561 T/A,IL28B rs12979860 C/T and ERα rs2077647 T/C polymorphisms with outcomes of hepatitis B virus infection:a meta-analysis显示文摘Several studies investigated associations of IFN-γ rs2430561 T/A,IL28 B rs12979860 C/T and ERα rs2077647 T/C gene polymorphisms with outcomes of hepatitis B virus(HBV) infection,but the results were controversial.Therefore,we performed a meta-analysis of all published observational studies to address this inconsistency.Literature was searched in online database and a systematic review was conducted based on the search results.A total of 24 studies were included and dichotomous data were presented as odds ratio(OR) with a 95%confidence interval(CI).The rs2430561 T allele was associated with reduced persistent HBV infection risk(T vs.A:OR,0.690;95%CI,[0.490,0.971]),while the rs2077647 T allele significantly increased the risk of persistent HBV infection(T vs.C:OR.1.678;95%CI,[1.212,2.3231).Rs 2077647 CC might play a role in protecting individuals against HBV persistence(TT vs.CC:OR,4.109;95%CI,[2.609,6.473]).Furthermore,carriers of the rs2430561 TT genotype were more likely to clear HBV spontaneously compared with those of the AA genotype(TT vs.AA:OR,0.555;95%CI,[0.359,0.856]).For rs12979860 C/T polymorphism,no significant correlation with HBV infection outcomes was found.In subgroup analyses,the results were similar to those of overall analysis.However,for rs2077647 TT vs.TC+CC,significantly increased risks were observed in the Asian and hospital-based population,but not in the overall analysis.IFN-γrs2430561 T/A and ERα rs2077647 T/C genetic polymorphisms were associated with outcomes of HBV infection,but no association was found between IL28 B rs12979860 C/T and HBV infection. | Shaidi Tang Ming Yue Jiajia Wang Yun Zhang Rongbin Yu Jing Su Zhihang Peng Jie Wang | 2014 | The Journal of Biomedical Research2014，28，6： | 2 |

| 10 | Effects and interaction of temperature and relative humidity on the trend of influenza prevalence:A multi-central study based on 30 provinces in China's Mainland from 2013 to 2018显示文摘Background:Evidence is inefficient about how meteorological factors influence the trends of influenza transmission in different regions of China.Methods:We estimated the time-varying reproduction number(Rt)of influenza and explored the impact of temperature and relative humidity on Rt using generalized additive quasi-Poisson regression models combined with the distribution lag non-linear model(DLNM).The effect of temperature and humidity interaction on Rt of influenza was explored.The multiple random-meta analysis was used to evaluate region-specific association.The excess risk(ER)index was defined to investigate the correlation between Rt and each meteorological factor with the modification of seasonal and regional characteristics.Results:Low temperature and low relative humidity contributed to influenza epidemics on the national level,while shapes of merged cumulative effect plots were different across regions.Compared to that of median temperature,the merged RR(95%CI)of low tem-perature in northern and southern regions were 1.40(1.24,1.45)and 1.20(1.14,1.27),respectively,while those of high temperature were 1.10(1.03,1.17)and 1.00(0.95,1.04),respectively.There were negative interactions between temperature and relative humidity on national(SI=0.59,95%CI:0.57e0.61),southern(SI=0.49,95%CI:0.17e0.80),and northern regions(SI=0.59,95%CI:0.56,0.62).In general,with the increase of the change of the two meteorological factors,the ER of Rt also gradually increased.Conclusions:Temperature and relative humidity have an effect on the influenza epidemics in China,and there is an interaction between the two meteorological factors,but the effect of each factor is heterogeneous among regions.Meteorological factors may be considered to predict the trend of influenza epidemic. | Yi Yin Miao Lai Sijia Zhou Ziying Chen Xin Jiang Liping Wang Zhongjie Li Zhihang Peng | 2023 | Infectious Disease Modelling2023，8，3： | 1 |

| 13 | Study on the COVID-19 epidemic in China's Mainland between November 2022 and January 2023,with prediction of its tendency显示文摘The prediction system EpiSIX was used to study the COVID-19 epidemic in China's Mainland between November 2022 and January 2023,based on reported data from December 9,2022,to January 30,2023,released by The Chinese Center for Disease Control and Prevention on February 1,2023.Three kinds of reported data were used for model fitting:the daily numbers of positive nucleic acid tests and deaths,and the daily number of hospital beds taken by COVID-19 patients.It was estimated that the overall infection rate was 87.54%and the overall case fatality rate was 0.078%–0.116%(median 0.100%).Assuming that a new COVID-19 epidemic outbreak would start in March or April of 2023,induced by a slightly more infectious mutant strain,we predicted a possible large rebound between September and October 2023,with a peak demand of between 800,000 and 900,000 inpatient beds.If no such new outbreak was induced by other variants,then the current COVID-19 epidemic course in China's Mainland would remain under control until the end of 2023.However,it is suggested that the necessary medical resources be prepared to manage possible COVID-19 epidemic emergencies in the near future,especially for the period between September and October 2023. | Yao Bai Zhihang Peng Fengying Wei Zhen Jin Jinjie Wang Ximing Xu Xinyan Zhang Jun Xu Zixiong Ren Bulai Lu Zhaojun Wang Jianguo Xu Senzhong Huang | 2023 | Journal of Biosafety and Biosecurity2023，5，1： | 1 |
